Paper Abstract

The formula for evaluation of narcissus equivalent temperature difference as a function of the scan angle in thermal imaging systems is made more meaningful by grouping the parameters in two factors: one depending on wavelength and temperature and the other, a function of the scan angle, depending on the geometry of the instrument. Exact ray tracing equations are used to evaluate the ratio of radiant energy reaching the detector from warm and cold areas of the instrument.
